28.5. Pixels in Parallel Converter IP Software API

The IP includes software for run-time control. The IP does not fit any of the generic device models provided by the Nios II HAL and it exposes a set of dedicated accessors to the control and status registers. The IP driver structure inherits the base driver structure so all common methods defined in Video and Vision Processing IPs Software API are applicable.

Register definition header file: intel_vvp_pip_conv_regs.h

Include file: intel_vvp_pip_conv.h

Table 446.  Pixels in Parallel IP API Reference
Name Description
intel_vvp_ pip_conv _init Initialize the pixels in parallel instance
Intel_vvp_core_* .Accessors defined in Video and Vision Processing IPs Software Programming Model . Writable when Lite is on. Readable when Lite is off and Debug features is on.
intel_vvp_pip_conv_get_lite_mode Returns if Lite mode is on
intel_vvp_pip_conv_get_debug_enabled Returns if Lite mode is on
intel_vvp_pip_conv_is_running Returns if the IP is processing data
intel_vvp_pip_conv_get_status Reads the status register

intel_vvp_pip_conv_init

Prototype
int intel_vvp_pip_conv_init(intel_vvp_pip_conv_instance *instance, intel_vvp_core_base base);
Description

Initializes a pip_conv instance. The initialization stops early if the vendor ID or product ID read at the base address are not a match or if the register map version is not supported. Otherwise, the function proceeds to read and store the IP compile-time parameterization. The instance does not fully initialized and should not be used further by the application if returning a non-zero error code.

Arguments

instance – pointer to the intel_vvp_pip_conv_instance software driver instance structure

base – base address of the register map

Returns

kIntelVvpCoreOk (0) in case of success, a negative error code in case of error

kIntelVvpCoreVidErr if the vendor id of the IP is not the Intel FPGA vendor ID (0x6AF7).

kIntelVvpCorePidErr if the product_id does not match with the Pixels in Parallel product ID

kIntelVvpCoreInstanceErr if the instance is a null pointer

kIntelVvpPipConvRegMapVersionErr if the register map is not supported

intel_vvp_pip_conv_get_lite_mode

Prototype
bool intel_vvp_pip_conv_get_lite_mode(intel_vvp_pip_conv_instance *instance);
Description
Returns the value of the LITE_MODE register. The instance must be a valid intel_vvp_pip_conv_instance fully initialized
Arguments

instance – pointer to the intel_vvp_pip_conv_instance software driver instance structure

Returns

true in case of success because the IP does not have an agent interface when parameterized in full mode

intel_vvp_pip_conv_get_debug_enabled

Prototype
bool intel_vvp_pip_conv_get_debug_enabled(intel_vvp_pip_conv_instance *instance);
Description

Returns the value of the DEBUG_ENABLED register. The instance must be a valid intel_vvp_pip_conv_instance fully initialized.

Arguments

instance – pointer to the intel_vvp_pip_conv_instance software driver instance structure

Returns

true if the IP is parameterized with debug features enabled

intel_vvp_pip_conv_is_running

Prototype
bool intel_vvp_pip_conv_is_running(intel_vvp_ pip_conv_instance* instance);
Description

Reads and returns the running bit of the STATUS register. The instance must be a valid intel_vvp_pip_conv_instance fully initialized.

Arguments

instance – pointer to the intel_vvp_pip_conv_instance software driver instance structure

Returns

True is the IP is currently generating an output field, false when disabled and/or between two fields

intel_vvp_pip_conv_get_status

Prototype
uint8_t intel_vvp_pip_conv_get_status(intel_vvp_pip_conv_instance* instance);
Description

Reads and returns the STATUS register. The instance must be a valid intel_vvp_pip_conv_instance fully initialized.

Arguments

instance – pointer to the intel_vvp_pip_conv_instance software driver instance structure

Returns

The value read from the status register
